Diagnostic Procedure 12 (Warning lamp does
not come on when ignition switch is turned
ON.)
CHECK FUSE.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Check 10A fuse
28. For fuse layout, refer
to POWER SUPPLY ROUTING in EL sec-
tion.
OK
cNG Replace fuse.
CHECK WARNING LAMP ACTIVATE.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Disconnect ABS actuator and electric unit
connector.
Does the warning lamp activate?
No

CHECK HARNESS FOR SHORT.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Disconnect ABS actuator and electric unit connector.
2. Check voltage between ABS actuator and electric unit connector
E18(body
side) terminal j
21and ground.
Battery voltage should not exist.
OK
cNG Repair harness or connec-
tor.
CHECK COMBINATION METER.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Turn ignition switch ``OFF''.
2. Disconnect ABS actuator and electric unit connector.
3. Check continuity between ABS actuator and electric unit connector
E18(body
side) terminal j
16and ground.
Continuity should exist.
OK
cNG Check the following.
+Harness connector
E18
+Harness for open or
short between ABS
actuator and electric unit
and ground
If NG, repair harness or
connector.
